William Dole Eckert, born on January 20, 1909, in Freeport, Illinois, is best remembered for his role as the fourth Commissioner of Major League Baseball, serving from 1965 to 1968. Before his tenure in baseball, Eckert had a distinguished military career in the United States Air Force, retiring as a lieutenant general. This military background, coupled with his educational pursuits at the United States Military Academy and Harvard Business School, equipped him with the management skills that would later define his contributions to baseball.

Eckert's entry into Major League Baseball was somewhat unconventional. Known as "Spike" during his military days, he was a relatively unknown figure in the baseball community when he was appointed Commissioner, having not attended a baseball game in over ten years prior to his appointment. His tenure as commissioner was marked by significant challenges, including the need to stabilize the league amidst growing business and operational pressures. He also faced criticism for his decision to continue games following the assassinations of Senator Robert F. Kennedy and Dr. Martin Luther King Jr., decisions that were unpopular with the public and the baseball community.

Despite these controversies, Eckert made notable contributions during his brief stint, including the promotion of baseball internationally and the initiation of more effective business practices within the league. His efforts helped pave the way for future developments in the sport, although his term was cut short when he was forced to resign in 1968 due to a lack of confidence from team owners, who were apprehensive about his ability to manage emerging crises, including labor disputes. Following his departure from baseball, Eckert remained a lesser-known figure in the annals of the sport's executives, yet his impact, particularly in international promotion and business optimization, continued to influence Major League Baseball. His career reflects a blend of military precision and a cautious foray into sports administration, characterized by both notable achievements and notable challenges.
